Lettere Pdtent No. 107,418, dated Sqfiehtber 13, 1870.

The Schedule referred, to in these Letters Ptentand making part of the same.

Ta all 2rhom it may concern:

Be it known that I, WILLIAM E. SPARKS, of New Haven, in the couixty et New Haven and State of Connecticnt, have invented a new lmprovement in upboard-Latches; and I do hereby declare the following, when taken in connection with the accornpanying dranings and the letters of reference marked thereon, to be a full, clear, and exact description et the Same, and which said drawings constitute part of this specification, and rcpresent in- Figure 1, a front v iew;

Figure 2, a section on line 9; x;

Figure 3, the latch-platc;

Figure 4, the latch;

Figure 5, the knob or lifter;

Figure 6, the reverse side of the lateh and in Figure 7, tire latcl1 in a reversed position.

This invention relates to an improvement in tirais class of latches known to the trade as eupboard-latches, that is, a small latch arranged upon a plate, to be fixed to tlne outside of the door, the object being to malte such latches reversiblefor a riglit or left-hand door.

The invention consists in the latch-head,-constrnet: ed with a pivot-point at one side of the center of the eaid latch-head, and combined with a knob or lifter upon adetaclzahle plate, whiclr is fixed to the latch and hung npon the same pivot with the lath.

A is the latch-plate, constructed with a guard, 13, so as to allow tlre necessary play for the latch, and with a bearing or pivot, npon which to bang tire lat-ch, the said pivot being in a central position relatiie to the guard B.

U, tlrelatch, is'constructed'as seen in fig. 4, and perforated at (1, to fit onto the bearin'g a, the said perand to insert a serew, D, through the said bearing. tu hold the plate in its place, and at the same time the latch upon tire plate; yet it may be readily seen that tire screiv itselt may' form the bearing, witlrout tlre pivot a formed on the plate.

.To thns reverse tire ltteh, it is necessary that the knob or lifter should be on the other side of tire latch.

T6 do this, I fix the knob E to a separate plate, F,

and form the said plate F with a stud or projection, j; te fit a scat, h, in tire latclr, and also extend tire said plate F bacl and perforate it, as at I), (see figs. 2 and 5,) corresponding to the perforation (1 in the latch, so that the same screw which secures the latchplate A, will also secure the plate F and its knob onto the latcln, as seen in figs.'l and 2.

I do not wish to be understood as hroadly claiming a reversible cupboard-Iatch, as such, I am aware,is

not 1iew; but

I do daim as my invention. v Tire latch-head O, constructed with tire pivot-poin (1, at one side of the center of the said latch-head, and

combined with the reversible knob or lifter E on the plate F, substantially in the manuel set forth.
